Benefits of technology

The present invention provides a sheet feeding device with a grooved elastic pad that solves problems of prior art such as uneven friction and wear and tear of the elastic pad. The device allows for smooth transport of sheets without bending or deformation. An image processing apparatus is also provided that includes the sheet feeding device and an image processing module for processing image data. The technical effects of the invention include improved sheet feeding and image processing.

Problems solved by technology

Due to the concentrated pressures on this small part of the friction pad 210, the friction pad 210 tends to wear out sooner than expected and consequently, decline in the quality of the sheet separation function will take place.

Embodiment Construction

[0019]The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

[0020]FIG. 1 is a schematic illustration of an image processing apparatus 1 according to a preferred embodiment of the present invention. FIGS. 2 and 3 are respectively an assembled view and an exploded view of an elastic pad and a feeding roller. As shown in FIGS. 1 to 3, the image processing apparatus 1 of the present invention, such as a scanner, a fax machine, a multi-function peripheral or a printer, is for transporting a sheet S into a transporting path 31. The image processing apparatus 1 includes a sheet feeding device 2, which includes an elastic pad 10 and a feeding roller 20. The image processing apparatus 1 further includes a body 30, a sheet-transporting mechanism 40, an image processing module 50, a biasing member 60 and a supply tray 70.

[0021]The supply tray 70, connected to the body 30, stores a plurality of sheets S, such a...

Abstract

A sheet feeding device, for transporting a sheet into a transporting path in an image processing apparatus, includes an elastic pad and a feeding roller for feeding the sheet. The elastic pad is bent and disposed opposite the feeding roller and applies an acting force to the feeding roller to separate the sheet from a stack of sheets by cooperating with the feeding roller. The elastic pad has a first side and an opposite second side. The second side is formed with a groove. The elastic pad is bent at an angle at the groove.

Description

[0001]This application claims priority of No. 099139945 filed in Taiwan R.O.C. on Nov. 19, 2010 under 35 USC 119, the entire content of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a sheet feeding device and an image processing apparatus using the same, and more particularly to a sheet feeding device with a grooved elastic pad and an image processing apparatus using the same.[0004]2. Related Art[0005]A conventional sheet separator of a scanner is usually composed of a feeding roller and a friction pad. FIG. 9 is a schematic illustration of a conventional friction pad 210 combined with a feeding roller 220. As shown in FIG. 9, a nip is formed between the feeding roller 220 and the friction pad 210 mounted on a body 230. The feeding roller 220 and the friction pad 210 separate an individual sheet (the bottommost sheet, in this case) from the stack of sheets SS, relying on the difference of th...
